Why does Smartly require marketing consent?

Smartly's pixel forwards conversion data to multiple ad platforms — Meta, TikTok, Pinterest, Snapchat — simultaneously. Each platform becomes an independent data controller, broadening the consent implications significantly beyond single-vendor ad tracking.

What does the Smartly pixel transmit on a conversion page?

On conversion pages, Smartly fires a beacon carrying transaction value, currency, product IDs, and a click reference ID read from the _smartly_cid cookie. This attribution data is relayed to each connected ad platform's conversion API for campaign measurement.

How does ConsentStack handle Smartly?

ConsentStack blocks Smartly's pixel until the visitor grants marketing consent. Once consent is confirmed, ConsentStack enables the pixel so conversion events fire and attribution data flows to connected ad platforms. Revoking consent causes ConsentStack to suppress subsequent Smartly beacons immediately.

What tracker domains does Smartly use?

ConsentStack has catalogued tracker domains for Smartly including smartly.io. These are the network destinations Smartly's scripts contact, which a consent platform blocks until a visitor agrees.

Smartly (smartly.io) - Social Ad Conversion & Tracking Consent

Back to Vendor Library

Overview

Smartly (formerly Smartly.io) is an advertising automation and creative management platform for paid social campaigns across Meta (Facebook/Instagram), TikTok, Snapchat, Pinterest, and Google Display. The platform combines dynamic creative production, media buying automation, and cross-channel attribution in a single interface. It serves performance marketing teams at mid-market and enterprise brands running high-volume paid social programs. When a Smartly conversion pixel appears on a website, it is tracking purchase completions and other conversion events to feed attribution data back into Smartly's optimization engine and the connected ad platforms.

What This Script Does

Smartly's pixel (smartly.io/pixel.js or a tag manager snippet referencing Smartly's tracking endpoints) fires on advertiser conversion pages and key funnel events:

Conversion tracking:

Fires a conversion beacon to Smartly's servers on order confirmation, sign-up completion, trial activation, and other goal pages
Transmits event metadata: transaction value, currency, product IDs (for catalog-based campaigns), conversion timestamp, and a click/session reference ID
Reads the _smartly_cid click cookie (first-party, 30-day expiry) set when a user clicks a Smartly-managed ad, enabling click-to-conversion attribution

Ad platform relay:

Smartly forwards conversion data to the relevant ad platform APIs — Meta Conversions API, TikTok Events API, Pinterest Conversion API, Snapchat Conversions API — to close the attribution loop within each platform's measurement system
This relay means a single Smartly pixel can satisfy conversion reporting requirements for multiple ad networks simultaneously

Audience and optimization:

Conversion data is used by the connected ad platforms to refine lookalike audience models and automated bid strategies
Smartly's own optimization layer uses cross-platform conversion signals to adjust campaign pacing and creative rotation

IAB TCF Purposes (when operating under a CMP):

Purpose 1: Store/access information on device
Purpose 3: Create personalized ad profile
Purpose 4: Select personalized ads
Purpose 7: Measure ad performance

Consent & Compliance

Category: Marketing / Analytics
GDPR: Requires explicit consent. Smartly's pixel collects behavioral data tied to ad campaign interactions and shares it with multiple third-party ad platforms, each of which becomes an independent data controller. This multi-party data sharing broadens consent implications significantly.
CCPA/CPRA: Constitutes "sharing" of personal information for cross-context behavioral advertising under CPRA. Must honor opt-out signals (Global Privacy Control).
ePrivacy: Sets and reads tracking cookies for click attribution. Consent required before any script load.
EU-US transfers: Smartly.io is a US entity (San Francisco). EU data transfers use Standard Contractual Clauses. The EU-US Data Privacy Framework may apply for participating entities.

Should You Block This Without Consent?

Yes. Smartly's pixel is a marketing attribution tracker that relays user data to multiple third-party ad networks. It should only fire after the visitor has given explicit consent for marketing or advertising cookies.

Is Smartly GDPR compliant?

Smartly typically loads marketing and analytics trackers, which are not strictly necessary for your site to work. Under the GDPR and the ePrivacy Directive, non-essential cookies and trackers must stay blocked until a visitor gives clear opt-in consent. So Smartly can be fully GDPR compliant, but only if your site holds its scripts until consent is granted and lets visitors decline just as easily. Compliance depends on how your site loads Smartly, not on Smartly itself.
